What is the sudden drop in idle speed of 50 forklift?

50 forklift truck idling suddenly low 1 `electromagnetic interference caused by insufficient idle power generation of alternator.

Insufficient idle power generation will lead to the nonlinear signal distortion of alternator, and electromagnetic interference will affect the fuel injector, which will cause the engine to shake slightly at idle speed and return to normal after starting.

2. When the engine speed is lower than1500rpm, the power is insufficient.

The nonlinear signal distortion of the generator sometimes affects the deflagration sensor, causing the deflagration sensor to send out the deflagration signal wrongly, causing the ignition advance angle of the engine to be delayed too much, resulting in obvious lack of power at idle speed and light load, leading to idle jitter and poor acceleration at light load.
